YATRICK H. WILLIAMS, OF NORTH WILKESBORO, NORTH CAROLINA, ASSIGNOR TO n Moenia Der xILN man. I

CO., OF JAGKSONVILLE, FLORIDA, A CORPORATION OF VENEER KILN.

Application led May 22, 1920. Serial No. 383,530.

To allwlwm. t may concern:

Be it knownv that I, PATRICK M. WIL- LIAMS, a citizen of the United States, resid' ing at North Wilkesboro, in the county of Wilkes and State of North Carolina, have invented certain new and useful Improvements in Veneer Kilns, of which the followin is a specification.

y invention relates to an improvement in dry kilns and the present invention is more particularly adapted to the drying of veneer and is an improvement on the La Fa ette 'Moore dry kiln system'.

n the accompanyin drawings Figure 1 is a oor p an view. Figure 2 is a longitudinal vertical section. Figures 3 and 4 are opposite end views. Figure 5 is a horizontal vertical section of the heating end of the kiln showing a 'modified form of my invention disclosing a baie to deflect the heat to the bottom of the kiln.

Figure 6 is a to plan view of the heating coil partially bro en away, and

Figure 7 is a vertical section of another modification of the heating end of the kiln showing a pair of bales to deflect the heat ltoward'the bottom of the kiln.

A, represents the kiln. This may be built on piers and longitudinal and transverse sills in the usual manner and it has a main track 1, running through it longitudinally substantially from one end to the other. At opposite ends vof the track there are provided loading and unloading transfer tracks 2 and 3 respectively. Storage tracks 1a may be provided at one side of the main track as shown in Figure 1. Doors 4, preferably of the sliding type, are providedy lfor closing the open ends where the transfer tracks are located.

A battery of heating coils 5, is located at one end of the kiln and a suction fan or fans 6, at the opposite end as .shown in 45 Figures 1 and 2. The roof 7, of the kiln dried air to expand and circulate rapidly through the length of the kiln under the inluence of the suction fans 6, at the opposite end of the kiln.

The size of the opening 8, is regulated and controlled by doors 9,' of which there are several, two being shown. These doors may be hinged or slide doors (not shown and the idea is that -the size of the openlng 8, may be varied according to the way these doors are adjusted and accordingly as a greater or less amount of air is to be sucked in through the opening 8,. .I

At intervals within the kiln I p-ropose to arrange sets of doors or flaps 10, swung upon two-way hinges 10 their' object being to close the space -at the surrounding edges of the body 11, of lumber carried upon the loaded truck 12, so that the heated air, so

far as possible is deiected and directed through the spaces between the lumber and prevented so far as 'possible from passing around it. l

Two sets only` of these two-way doors or flaps 10, are shown in Figure 1, but more or even less might be employed and they are located at top, bottom and on the side Walls of the kiln and are of a width to fill' the space between the normal load of a truck and the roof, floor, and walls of the kiln, and these two-way doors or iiaps are mounted on spring hinges and 'in position `to be swungaside by the truck and its load.

From the foregoing it will be seen that the air immediately upon entering the kiln must come in contact with the coils; that the amount of air admitted may be regulated; that this air upon beingl heated and expanded is directed through the lumber and revented from circulating around it where its effect would be lost. A

Either one or two suction fans or even more might be employed, two 'only bein shown. These are driven by belts 13y an While I have shown only three sets of coils at the pipe end it is obvious that even more or less may be employed; also that the dimensions of the kiln might be varied asl well as the material used in its construction without departure from my invention.
